Quizplus · Accepted Answer

Metadata is information about data, including how it is organized, the meaning of the data fields, and how to use the data effectively. A data directory provides a list of files or data sets, a data index is a list of keywords or terms used to locate data, and data fields are specific pieces of information within a data record. While all of these components are important in understanding data within a data warehouse, metadata specifically addresses how the data is organized and how it can be effectively used.
